Improved Grab (Ex): If a lurker hits a Medium or smaller opponent with its slam attack, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity (grapple bonus +12). If it gets a hold, it wraps itself around the victim and constricts.

Any attacks that hit a lurker while it is wrapped around a foe deal half their damage to the monster and half to the trapped victim.
